I walked out on my porch to look through my new telescope. As I was putting it together I looked up to see where the moon was so I could adjust my telescope accordingly. As I stared in the sky I witnessed a solid moving object that made no sound. I move from West to East at what appeared to be 5-10 mph. It had no visible lights which threw me because I always invisioned an UFO having quiet a few lights. I watched as it slowly went overhead for about a minute. It never changed speed or made a sound. Because it was dark, I could only make out that it was what appeared to be a diamond shape.
